Very little is known of depressed patients' mental state after being discharged from inpatient wards where they are provided with a sheltered environment with stable sleep wake cycle, regular meals, and regular physical and social activities. Our previous usability study, SAFE I, showed that electronic self-monitoring was a useful tool to gain insight into patients' condition in the weeks after discharge. Results showed that patients over a four week period had significant day to day variations in self-rated mood and sleeping schedule and that the patients' sleep patterns were delayed with 45 minutes.
